The Yamaha YSL-350C is a uniquely designed compact tenor trombone, perfect for young players, individuals with shorter arm reach, or situations requiring a more manageable instrument. Its standout features include:
-
Compact design with full-range capability – It maintains full trombone functionality while being shorter in length, thanks to its ascending rotor valve, which enables a full scale without using extended slide positions .
-
Standard slide positions – The slide positions match those of a regular trombone, so players don’t need to adjust or learn new positions
-
Enhanced balance and portability – The shorter profile offers improved balance and easier handling, making it suitable for both children and adults
